Enthalpy of solvation of butanediols in different solvents

The enthalpies of solution for 1,2-, 1,3-, 1,4- and 2,3-butanediol in water , formamide and dimethylsulphoxide were determined by calorimetry. From the results and data available in the literature for the enthalpy of vaporisat ion, the enthalpy of solvation was determined. The enthalpy of solvation wa s decomposed into two terms, cavity formation in the solvent to hold the so lute and solute-solvent interaction. (C) 2000 Elsevier Science B.V. All rig hts reserved.
